Hello jrelyea, 

Indeed this has been discussed a number of times. In order for the XamDataGrid to show headers it needs to have an usable FieldLayout, meaning that whether there is only or many FieldLayouts declared in the collection the XamDataGrid will use one that which Fields match the DataSource’s properties. For this of course some DataSource must be said. Here is also a more detailed description of the properties/Fields matching logic: http://es.infragistics.com/community/blogs/petar_monov/archive/2011/05/13/how-to-define-fieldlayouts-how-fieldlyouts-are-mapped.aspx . 

When it comes to UnboundFields and if the whole FieldLayout consists only of UnboundFields e.g.:

<igDP:FieldLayout  >

    <igDP:FieldLayout.Settings>

        <igDP:FieldLayoutSettings AutoGenerateFields="False"  />

    </igDP:FieldLayout.Settings>

    <igDP:UnboundField Label="Name" />

    <igDP:UnboundField Label="Age" />

    <igDP:UnboundField Label="Salary" />

</igDP:FieldLayout> 

there is nothing to match, however there still should be some DataSource set. Even this works: 

xamDataGrid1.DataSource = "";

Please let me know, if I can be of any further assistance on the matter.
